The present invention is directed to a process for producing a modified olefin polymer having increased melt strength in an extruder. The process comprising the steps of: (A) contacting a stream comprising particles of an olefin polymer with a vapour stream of a functionally unsaturated compound in vapour phase thereby producing a first mixed stream; (B) passing the first mixed stream to an extruder; (C) melting the polymer particles of the first mixed stream in the extruder; (D) introducing a stream of a free radical generator either into the first mixed stream or into the extruder; and (E) extruding the first mixed stream and the free radical generator at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder.

The present invention relates to wash oil for use as an antifouling agent in gas compressors, in particular in cracked gas compressors, including at least one compound according to formulae (II)  with the moieties Rand Rare selected from a group of linear or branched C-C-alkyl, C-C-cycloalkyl and linear or branched C-C-alkyl substituted C-C-cycloalkyl and C-Caryl and C-C-alkyl substituted C-Caryl. The moieties can be interrupted by oxygen or nitrogen. The moieties can be functionalised with hydroxyl groups or amino groups. The moieties can be the same or different. The invention relates also to the use of such wash oil as anti-fouling agent.
